Abstract (en)
[origin: US2018298683A1] A window shade includes a reel coupled to a first control module and connected with a panel assembly, a lift actuator coupled to a second control module, and a switchable coupling mechanism. The panel assembly has an open state for light passage and a closed state blocking light passage. The first control module can drive the reel in rotation for winding and unwinding the panel assembly. The second control module can drive the lift actuator in rotation for switching the panel assembly to the open or closed state. The coupling mechanism has a coupling state in which it rotationally couples the lift actuator to the first control module, and an uncoupling state in which it rotationally uncouples the lift actuator from the first control module. The coupling mechanism is in the uncoupling state while the panel assembly is closed, and in the coupling state while the panel assembly is opened.
